Description

Technical Field

[0001] This utility model belongs to the field of vehicle technology, and in particular relates to a front anti-collision beam mounting structure, chassis assembly and vehicle. Background Technology

[0002] Hollow buffer beams protrude from the rear sides of both ends of the front anti-collision beam. The rear end of the buffer beam has a second pair of holes that pass through laterally. Hollow longitudinal beams are located on both sides of the chassis body. The front end of the longitudinal beam has a first pair of holes that pass through laterally. The front anti-collision beam is installed at the front of the chassis by inserting the two buffer beams into the two longitudinal beams respectively until the first pair of holes and the second pair of holes are exactly aligned. At this point, the two are connected by bolts that pass through the first pair of holes and the second pair of holes. However, in actual operation, the depth of insertion of the buffer beam into the longitudinal beam needs to be tried multiple times until the first pair of holes and the second pair of holes are aligned, which will reduce production efficiency. Utility Model Content

[0003] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a simple and easy-to-assemble anti-collision front beam mounting structure.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: A front anti-collision beam mounting structure includes a chassis body and a front anti-collision beam. The chassis body has hollow longitudinal beams arranged along the front-rear direction on both sides. Hollow buffer beams protrude from the rear ends of both sides of the front anti-collision beam. The front end of the longitudinal beam is provided with a first pair of holes penetrating through its opposite sides. The rear end of the buffer beam is provided with a second pair of holes penetrating through its opposite sides. The rear ends of the two buffer beams are respectively inserted into the longitudinal beams on the corresponding sides. When the first pair of holes and the second pair of holes are aligned with each other, bolts are inserted to connect them. The front end of the longitudinal beam is provided with a limiting male part, and the rear end of the buffer beam is provided with a limiting female part. When the buffer beam is inserted into the longitudinal beam and the limiting male part and the limiting female part cooperate, the first pair of holes and the second pair of holes are aligned with each other.

[0005] The beneficial effects of the above-mentioned technical solution of this utility model are as follows: the two buffer beams on the front anti-collision beam can be directly inserted into the corresponding two longitudinal beams until the male limiting part and the female limiting part cooperate, which means that the first pair of holes and the second pair of holes are aligned. At this time, the bolts can be directly inserted for connection, which makes the installation of the front anti-collision beam on the chassis body more convenient.

[0006] Based on the above technical solution, the present invention can be improved as follows: Furthermore, the limiting male part is a notch recessed in the front side wall of the longitudinal beam, and the limiting female part is a protrusion protruding in the corresponding position on the outer wall of the buffer beam; or the limiting male part is a protrusion protruding in the inner wall of the front end of the longitudinal beam, and the limiting female part is a notch recessed in the front side wall of the buffer beam.

[0007] The beneficial effect of the above-mentioned further technical solution is that the two buffer beams on the front anti-collision beam can be directly inserted into the corresponding two longitudinal beams until the male limiting part and the female limiting part abut against each other, which means that the first pair of holes and the second pair of holes are aligned.

[0008] Furthermore, when the limiting mother part is a protrusion, a weakening gap is provided at the connection between the limiting mother part and the buffer beam.

[0009] The beneficial effect of the above-mentioned further technical solution is that when the front anti-collision beam is subjected to a rearward impact force, the limiting mother part can be sheared away by the longitudinal beam, thus avoiding the limiting mother part from shearing the limiting male part and affecting the structural damage of the longitudinal beam.

[0010] Furthermore, when the limiting part is a notch or groove, a reinforcing rib is provided on the longitudinal beam at the edge corresponding to the limiting part.

[0011] The beneficial effect of the above-mentioned further technical solution is that it makes the longitudinal beam have high structural strength at the position of the limiting part.

[0012] Furthermore, both sides of the front end of the longitudinal beam are provided with outwardly inclined guide skirts.

[0013] The beneficial effect of the above-mentioned further technical solution is that it makes it more convenient to insert the rear end of the buffer beam into the front end of the longitudinal beam.

[0014] Furthermore, the longitudinal beam has multiple male limiting parts, and the buffer beam has multiple female limiting parts, with each male limiting part corresponding to one female limiting part.

[0015] The beneficial effect of the above-mentioned further technical solution is that it makes the rear end of the buffer beam better guided into the longitudinal beam when the anti-collision front beam is assembled at the front end of the chassis body.

[0016] Furthermore, each of the longitudinal beams has two male limiting parts, and the two male limiting parts on each longitudinal beam are distributed opposite to each other; each of the buffer beams has two female limiting parts, and the two female limiting parts on each buffer beam are distributed opposite to each other.

[0017] The beneficial effect of the above-mentioned further technical solution is that it makes the rear end of the buffer beam better guided into the longitudinal beam, while not affecting the structural strength of the longitudinal beam and the buffer beam.

[0018] Furthermore, the first pair of holes at the front end of the longitudinal beam is provided with multiple holes, and the second pair of holes at the rear end of the buffer beam is also provided with multiple holes, and the multiple first pair of holes and the multiple second pair of holes correspond one-to-one.

[0019] The beneficial effect of the above-mentioned further technical solution is that it makes the connection strength between the longitudinal beam and the front anti-collision beam higher.

[0020] The second objective of this utility model is to provide a chassis assembly that is simple in structure and easy to assemble.

[0021] To achieve the above objectives, the technical solution of this utility model is as follows: a chassis assembly, including the anti-collision front beam mounting structure as described above.

[0022] The beneficial effects of the above-mentioned technical solution of this utility model are that the chassis body and the front anti-collision beam of the chassis assembly are easy to install.

[0023] The third objective of this utility model is to provide a chassis assembly that is simple in structure and easy to assemble.

[0024] To achieve the above objectives, the technical solution of this utility model is as follows: a vehicle, including the chassis assembly as described above.

[0033] Example 1 like Figures 1-7 As shown, this embodiment provides a front anti-collision beam mounting structure, including a chassis body 1 and a front anti-collision beam 2. The chassis body 1 has hollow longitudinal beams 11 arranged along the front-rear direction on both sides. Hollow buffer beams 21 protrude from the rear ends of both sides of the front anti-collision beam 2. The front end of the longitudinal beam 11 is provided with a first pair of holes 111 penetrating through its opposite sides, and the rear end of the buffer beam 21 is provided with a second pair of holes 211 penetrating through its opposite sides. The rear ends of the two buffer beams 21 are respectively inserted into the longitudinal beam 11 on the corresponding side, to the first pair of holes 111 and the second pair of holes 211. When aligned, the bolts 3 are inserted to connect them. In order to enable the buffer beam to be quickly inserted into the corresponding longitudinal beam (i.e., the first pair of holes 111 and the second pair of holes 211 are exactly aligned), the core improvement of this embodiment compared with the prior art is that a limiting male part 112 is provided at the front end of the longitudinal beam 11 and a limiting female part 212 is provided at the rear end of the buffer beam 21. When the buffer beam 21 is inserted into the longitudinal beam 11 and the limiting male part 112 and the limiting female part 212 are engaged, the first pair of holes 111 and the second pair of holes 211 are aligned with each other. This allows the two buffer beams 21 on the front anti-collision beam 2 to be directly inserted into the corresponding two longitudinal beams 11 until the male limiting part 112 and the female limiting part 212 are engaged, indicating that the first pair of holes 111 and the second pair of holes 211 are aligned. At this point, the bolts 3 can be directly inserted for connection. This makes the installation of the front anti-collision beam 2 on the chassis body 1 more convenient (and can shorten the assembly time of the front anti-collision beam 2 at the front end of the chassis body 1).

[0034] In this embodiment, the front end of the longitudinal beam 11 and the rear end of the buffer beam 21 are both square-shaped.

[0035] like Figures 2-5 and Figure 7As shown, in this embodiment, the first pair of holes 111 includes two first connecting holes 1111 located on opposite sides of the front end of the longitudinal beam 11, and the two first connecting holes 1111 are aligned with each other; the second pair of holes 211 includes two second connecting holes 2111 located on opposite sides of the rear end of the buffer beam 21, and the two second connecting holes 2111 are aligned with each other.

[0036] like Figure 2 and Figure 7 As shown, in this embodiment, the bolt 3 includes a bolt 31 and a nut 32. The bolt 31 passes through the first pair of holes 111 and the second pair of holes 211 that are aligned with each other, and the nut 32 is threadedly connected to the threaded end of the bolt 31.

[0037] In this embodiment, the front anti-collision beam 2 is a protective beam used to absorb collision energy when the vehicle is involved in a collision. It reduces the injury to passengers in the vehicle to a certain extent, and at the same time minimizes the damage of the impact force to the longitudinal beam 11 (in order to reduce the maintenance cost of the vehicle in the later stage). The key component of the front anti-collision beam 2 that plays a role in buffering and absorbing energy is the buffer beam 21. Therefore, the structural strength of the buffer beam 21 is lower than that of the longitudinal beam 11.

[0038] like Figures 1-6 As shown, in this embodiment, the limiting male part 112 is a notch recessed in the front side wall of the longitudinal beam 11, and the limiting female part 212 is a protrusion protruding from the corresponding position on the outer wall of the buffer beam 21. When the buffer beam 21 is inserted into the longitudinal beam 11, the limiting female part 212 and the limiting male part 112 are aligned front to back. When the limiting female part 212 and the limiting male part 112 are inserted into place, the first pair of holes 111 and the second pair of holes 211 are aligned with each other. The two buffer beams 21 on the front anti-collision beam 2 can be directly inserted into the corresponding two longitudinal beams 11 until the limiting male part 112 and the limiting female part 212 abut against each other, which indicates that the first pair of holes 111 and the second pair of holes 211 are in an aligned state.

[0039] like Figure 6 As shown, in this embodiment, a weakening gap 213 is provided at the connection between the limiting female part 212 and the buffer beam 21. This allows the limiting female part 212 to be sheared away by the longitudinal beam 11 when the front anti-collision beam 2 is subjected to a rearward impact force, thus preventing the limiting female part 212 from shearing against the limiting male part 112 and causing structural damage to the front end of the longitudinal beam 11. Specifically, the limiting female part 212 can be partially spot-welded to the buffer beam 21 (in this case, the unwelded position on the mating surface of the limiting female part 212 and the buffer beam 21 constitutes the weakening gap 213).

[0040] like Figure 5As shown, in this embodiment, the outer wall of the longitudinal beam 11 is thickened at the edge corresponding to the limiting part 112 to form a "U"-shaped reinforcing rib 113. This makes the longitudinal beam 11 have high structural strength at the position of the limiting part 112.

[0041] like Figures 2-5 As shown, in this embodiment, the longitudinal beam 11 has outwardly inclined guide skirts 114 protruding from both sides of its front end. This makes it easier to insert the rear end of the buffer beam 21 into the front end of the longitudinal beam 11.

[0042] Preferred, such as Figure 5 As shown, in this embodiment, the slot of the limiting part 112 is flared in the shape of an "eight" (i.e., the slot of the notch is flared in the shape of an "eight"), which makes it play a guiding role, thus making it more convenient for the buffer beam 21 and the corresponding longitudinal beam 11 to be inserted.

[0043] In this embodiment, a limiting male part 112 may be provided on only one longitudinal beam 11, and a limiting female part 212 may be provided on only the buffer beam 21 on the same side (the longitudinal beam 11 and buffer beam 21 on the other side may be provided or not). For a single longitudinal beam 11, a limiting male part 112 may be provided on at least one side.

[0044] Preferably, in this embodiment, multiple male limiting parts 112 are provided on the longitudinal beam 11, and multiple female limiting parts 212 are provided on the buffer beam 21, with each male limiting part 112 corresponding to one female limiting part 212. This improves the guiding effect of the rear end of the buffer beam 21 into the longitudinal beam 11 when the front anti-collision beam 2 is assembled at the front end of the chassis body 1.

[0045] Further preferred, such as Figures 1-6 As shown, in this embodiment, each longitudinal beam 11 has two limiting male portions 112, and the two limiting male portions 112 on each longitudinal beam 11 are relatively distributed; each buffer beam 21 has two limiting female portions 212, and the two limiting female portions 212 on each buffer beam 21 are relatively distributed. This makes the rear end of the buffer beam 21 more guide when inserted into the longitudinal beam 11, without affecting the structural strength of the longitudinal beam 11 and the buffer beam 21.

[0046] Specifically, in this embodiment, a limiting male part 112 can be provided on the left and right sides of each of the longitudinal beams 11, and a limiting female part 212 can also be provided on the left and right sides of the corresponding buffer beams 21.

[0047] like Figures 3-5As shown in the figure, in this embodiment, a plurality of first pairs of holes 111 at the front end of the side rail 11 are provided, and a plurality of second pairs of holes 211 at the rear end of the crash cushion beam 21 are also provided, and the plurality of first pairs of holes 111 correspond to the plurality of second pairs of holes 211 one by one. This enables higher connection strength between the side rail 11 and the front impact beam 2. Preferably, 2 to 4 first pairs of holes 111 on the side rail 11 and 2 to 4 second pairs of holes 211 on the crash cushion beam 21 are sufficient (specifically, 2, 3 or 4).

[0048] In this embodiment, both the notch groove and the protruding block are straight strip-shaped.

[0049] Embodiment 2 Same as Embodiment 1, with the difference that, as shown in Figure 8 and Figure 9 , in this embodiment, the male limiting portion 112 is a protruding block protruding from the inner wall of the front end of the side rail 11, the male limiting portion 112 in this embodiment may be integrally formed with the side rail 11, and the female limiting portion 212 is a notch groove recessed at the side wall of the front end of the crash cushion beam 21 (in this embodiment, the notch of the notch groove is also in an "eight-shaped" flared shape). This enables better structural strength of the front end of the side rail 11. When the front end of the vehicle is collided, even if the crash cushion beam 21 is damaged, the side rail 11 will not be easily damaged.

[0050] Of course, as shown in Figure 10 , the two male limiting portions 112 can also extend to be integrated into one piece. At this time, the interior of the front end of the side rail 11 is in a "grid-shaped" structure, which enables higher structural strength of the front end of the side rail 11.

[0051] Embodiment 3 This embodiment provides a chassis assembly, comprising the front impact beam mounting structure according to Embodiment 1 or 2. The chassis body 1 and the front impact beam 2 of the chassis assembly are convenient to mount.

[0052] Embodiment 4 This embodiment provides a vehicle, comprising the chassis assembly according to Embodiment 3. The assembling efficiency of the chassis body 1 and the front impact beam 2 of the vehicle is high.

[0053] The above description is only preferred embodiments of the present utility model, and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
